Copper(II) Carbonate Dihydroxide(Cat No.: R045057), also known as basic copper carbonate or malachite (Cu₂(OH)₂CO₃), is a green, crystalline compound used in pigments, ceramics, and as a precursor in copper salt production. It occurs naturally as a mineral and is insoluble in water but reacts with acids to release carbon dioxide. In chemistry labs, it’s employed in educational demonstrations and small-scale reactions. Its antimicrobial and antifungal properties also find limited use in agricultural formulations and wood preservatives. Handle with care to avoid dust inhalation.
